I want to move a rigid object with following command

So, I want a rigid body to move 24 things on the x axis when i collide with an object but when i run the program i get this error: Assets/Scripts/PlayerMovement.cs(38,51): error CS0029: Cannot implicitly convert type float' to UnityEngine.Vector3'

This's my code:

using UnityEngine; using System.Collections;

 public class PlayerMovement : MonoBehaviour {
     public float moveSpeed;
     public GameObject deathParticles;
 
     private float maxSpeed = 5f;
     private Vector3 input;
     private Vector3 spawn;
     public Vector3 location;
 
     void Start () {
         spawn = transform.position;
         location = transform.position;
     }    
 
     void Update () {
         input = new Vector3(Input.GetAxisRaw ("Horizontal"), 0, Input.GetAxisRaw("Vertical"));
         if(rigidbody.velocity.magnitude < maxSpeed)
         {
             rigidbody.AddForce(input * moveSpeed);
         }
 
     }
 
     void OnCollisionEnter(Collision other)
     {
         if (other.transform.tag == "Enemy") {         
 
                 Die ();
                 
         }
     }
 
     void OnTriggerEnter(Collider other) {
                 if (other.collider.tag == "NextLevel001") {
                     transform.position = location.x + 24;
             }
     }
 
     void Die() 
     {
         Instantiate(deathParticles, transform.position, Quaternion.identity);
         transform.position = spawn;
     }
 }

Help would be gladly appreciated :)
